Specification of Letters Patent.

Application filed June 29, 1915.. Serial No. 37,011. v

To all whom it may concern.

Be it known that I, EDGAR C. HILL, a citi Zen of the United States of America, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in J ar-Closures, of which the following is a specification.

The present invention appertains to an improved jar closure, and is designed to provide a device which is comparatively'simple in construction and operation, durable, and inexpensive in cost of production.

The primary object of the invention is the provision of a device capable of imparting a wedge action to clamp the jar lid or top tightly upon its gasket in such manner that 1 the device may be readily locked in place and with equal facility be unlocked when desired to open the jar. V

The invention consists in certain novel combinations and arrangements of parts of a spider look as will be hereinafter more I fully set forth.

The accompanying drawings depict the best mode I have sofar devised for the practical application of the principles of my invention, in which Figure 1 is a side view of the toppart of a glass or other jar having its lid locked by my device. Fig. 2 is a sectional view showing a part of the device to illustrate the wedge action of the closure in clamping the jar top to the jar. Fig. 3 is a top plan Fig. 4 illustrates the same device unlocked.

In the preferred embodiment of the invention as illustrated in the drawings I employ a bridge piece formed with two arms 1 and 2 and each of these arms is fashioned with a hook as 3, while the extremity of each arm is beveled as at 4. A. third arm 5 completes the three points of attachment of the locking device, and this arm is also hooked at beveled ring 11 under the flange 12 at the V Patented Feb. 8, 1916.

mouth of the jar. To accomplishthis clamping function I employ alever pivoted at 13 on the; bridge piece whose handle is provided by the long arm 14 and the short arm 15 of this operating lever is pivotally connected at 16 to the movable arm 5.

The operation andfunctions of the device are graphically illustrated in the drawings wherein Fig. 4 shows the device unlocked 7 and Fig. 3 illustrates the locked position.

The two hooks of the bridge piece are first slipped over the jar top to be clamped .with their beveled ends under the beveled ring 11 of the jar and then the loose hook 7/is positioned as in Fig. 4. The operating lever handle 14 is, then turned on its pivot 13 to swing the pivot point 16 around, and past a line made by the two pivot points and the hook 7 ,inotherwords beyond the dead center. It will be noted that the operating lever is permitted to swing under the pivoted end of the pivoted arm 5 and the pivotedend of the arm is offset forthis purpose forming a shoulder 5 against which the operating lever is brought when its short arm has been brought beyond the dead 'center.. In this manner the lever is held in position and the hooks'are locked about the jar top. The action of the lever draws the hooked end 7 of the pivoted arm toward the bridge piece and the consequence is that the three beveled ends 4, 4 and 7 of the clamp arms are frictionally engaged and drawn under the beveled ring 11 of the jarwith the resultthat thetop is clamped down tightly upon the.

gasket to make a securejoint. When it is desired to unlock the parts the lever is turned in the direction of the arrow in Fig. 4 and the pivoted arm 5 swung in the direction of its arrow, and then the entire device may be displaced from the jar top. In this way I provide a locking device which may be manipulated with facility and despatch, and which performs its functions in a comparatively perfect manner.

' What I claim is I 1. A locking device comprising a bridge piece with angular arms formed each with a hook and'a beveled, end, combined with a of said piece, and an arm pivoted on the short arm of said lever having an end hook and beveled end and formed With a shoulder to provide a stop for said lever.

In testimony whereof I my signature.

long arm and a short arm, and a third arm formed With a hook and beveled end and pivoted on the short arm of said lever.

2. A locking device comprising a single 5 angular piece formed With end hooks and beveled ends, an operating'lever having a long arm and a short arm pivoted centrally Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
